OK I know you guys might be looking at Gadius and going zomg he has 2 rows.
But Juggler with 4x Pandora subs = 8 dark rows
Gadius with any combination of Yamato Takeru / Uriel subs = 8 red rows
They are actually equal in terms of row count. Juggler is still better cause he has x7 over x6. But, Gadius has the benefit of having about 6x more RCV, he can at least do x4?
? with one heart match. Anyway Gadius (some people will romanize it Godius which I won't argue against either because there is a Japanese MMO called Godius which uses the same katakana) is pretty much better than the others at a first glance. Problem with Illum and Zuoh is that their x6 requires 4 combo of 2+2, which is pretty difficult to acquire at times without some orb manipulations or sick orb management. If you are gonna use Illum's L/R sonia active you are gonna want to pray that you can do the 3+3 rows or something very close to it. Zuoh is just not that great due to awakenings, at least Illum has Finger.
As for Typhon, we don't have a clue about the lower bound of the ATK multiplier and we don't know as of now how many hearts could be eliminated in order to get x6.
Regarding Kaguya-hime, you can't do Osiris System unlike using GZL leads, because you won't have enough Skill Boosts to have Osiris up on turn 1, since Osiris himself don't have Skill Boost.
>weaker ariel active
okay not entirely cool
Well, honestly, same thing was thrown around with Grimoire Descend compared to their REM counterparts Ass Nova and Goetia (2 < 3) but eventually people forgot about it due to the Enhance aspect. As for Kaguya-hime, yeah, this is actually a problem because they both have the same max skilled CD. Though Ariel can't be skilled up without Pii at least. Anyway, Kaguya-hime should have had CD 3 at max level. That would be OK.
